Detailed description

1. TR-9300D flue gas ultra-low emission continuous monitoring system

Ultra low emissions refer to the use of multiple pollutant collaborative removal integrated system technologies in coal-fired boilers of thermal power plants during power generation operation and end treatment processes, so that their atmospheric pollutant emission concentrations basically meet the emission limits of gas turbines. That is, the emission concentrations of smoke, sulfur dioxide, and nitrogen oxides (with a reference oxygen content of 6%) do not exceed 5 mg/m ³, 35 mg/m ³, and 50 mg/m ³, respectively. This is a new benchmark for the clean production level of coal-fired generator units, which is 50%, 30%, and 50% lower than the special emission limits for coal-fired boilers in key areas specified in the Air Pollutant Emission Standards for Thermal Power Plants (GB13223-2011).

In response to this background, Xi'an Juneng Instrument Co., Ltd. has successfully launched the TR-9300D ultra-low emission continuous monitoring system for flue gas, based on years of experience in research and application of environmental monitoring systems. The system is based on relevant standards and specifications such as HJ/T76-2007 and HJ/T75-2007. The analytical instrument used is the JNYQ-S-81 flue gas analyzer independently developed by Xi'an Juneng Instrument Co., Ltd. A single monitoring system adopts an architecture mode of monitoring platform probe+preprocessing+industrial computer+LCD display+data acquisition instrument to complete the functional requirements of receiving, storing, displaying, and transmitting monitoring data.

 

2. Monitoring plan for gaseous pollutant factors

Using a fully extraction system and a dedicated ultra-low smoke heating sampling probe, the smoke is extracted from the flue and transmitted through heat tracing. The smoke is then transported to the smoke analysis cabinet for dust removal, ultra-low emission smoke special condenser for water removal, and enters the JNYQ-S-81 smoke analyzer for monitoring and analysis. The monitoring data is then transmitted to the industrial control computer and data acquisition instrument for storage and transmission. The analyzer adopts the DOAS method, which is based on the narrowband absorption characteristics of the substance molecules to distinguish and invert the concentration of the gas being measured. It is not affected by other interfering gases such as water vapor, and the measurement principle determines that the zero point of the instrument has basically no drift.
